WHAT IS TREE TOPOLOGY ?

Imagine a hierarchy of network nodes, with the root node serving client nodes, that in turn serve other lower-level nodes. The top-level node is mostly a mainframe computer while other nodes in the hierarchy are mini or microcomputers. In this arrangement, the node at each level could be forming a star network with the nodes it serves. In this case, the structure combines star and bus topologies and inherits their advantages and disadvantages.

Advantages of Tree Topology

1. It is an extension of Star and bus Topologies, so in networks where these topologies can’t be implemented individually for reasons related to scalability, tree topology is the best alternative.
2. Expansion of Network is possible and easy.
3. Here, we divide the whole network into segments (star networks), which can be easily managed and maintained.
4. Error detection and correction is easy.
5. Each segment is provided with dedicated point-to-point wiring to the central hub.
6. If one segment is damaged, other segments are not affected.

Disadvantages of Tree Topology

1. Because of its basic structure, tree topology, relies heavily on the main bus cable, if it breaks whole network is crippled.
2. As more and more nodes and segments are added, the maintenance becomes difficult.
3. Scalability of the network depends on the type of cable used.
